ALARM FR AUTOMOBILES.

nordsee.

To all whom it may concrn:

Be it yknown that l, lVlLsoN E. Simons, a citizen of the United States, residing at Chicago, in the county of Cook and State ot' Illinois, have invented a new and useful Alarm for Automobili-sid which the following is a specification.

The invention relates to an alarm for automobiles.

The object of the present Iinvention is to provide for automobiles a simple, eitticient and comparatively inexpensive device, adapted, should any unauthorized person attemptto crank an automobile, to sound an alarm, which will either frighten away the thief, or through-its continuous ringing attract attention and give notice 'that the automobile has been stolen or an attemptmade to steal it.

A further object of the invent-ion is to -Y provide analarrn of this character, adapted size and minor details of construction, with- 1 in the scope of the claims, may be resorted to without departing from the spirit or sacrificing any'ot the advantages of the invention.

ln the drawings :-l*`igure 1 is a sideelevation, part-ly in section, of an alarm, con structed in accordance with this invention and shown applied to a portion of an automobile. Fig. 2 is a plan view of the same. Fig is a frontelevation, the side beams or members 'of thetrame of the automobile being in section. Fig. 4. is a detail sectional view, illustrating the manner of mounting .the-*starting crank and the alarm operating shaftf Fig. 5 is a 'detail sectional view on the lin-e 5-5 of the Fig. 1. Fig. 6 is adetail perspective 'view of the bearing bracket. ,litiga` 7 is` a detail view partly in section, showingan electrical alarm.. t

responding parts in allthe figures of the drawings.

Inth'e accompanying drawings in which tening'devices to the front transverse bar or beam 4t of an automobile frame at the center of the said bar or beam, as clearly illustrated in Fig. 3 of the drawings. The bracket is provided at an intermediate point -with a horizontal bearing opening 5 for the receptionl ot' the shaft or spindle portion 6 of4 the starting crank 7. The bearing bracket" is also provided'with a lower rear wardly extending portion 8, which is forked or bifurcated to provide spaced sides 9, between which is arranged a short inner arm 10 of a transverse operating shaft 11. The operating shaft 11 is journaled at its inner end in opposite bearing openings 12 voi" the spaced sides 9, andv the shortinner arm 10 is provided with a hub or sleeve 13, which is secured by a pin 14, or other suitable fastening device to the shaft 11. The short arm 10 extends upward into the path of the inner toothed end or head 15 of theshaft portion 6 of the starting crank, and is adapted to be engaged and oscillated by the same when the startingcrank is moved inwardly to engage it with the outer end of the engine shaft 16. The outer end of the engine shaft 16 is provided with opposite projections 17, arranged to be vengaged by bolts 22,0r other suitable fastening devices.

The outer arm 20 is provided at its upper end with an opening 23 into which is linked an eye 24 of a longitudinal connecting rod 25, which extends forwardly to a trigger 26 of an alarm 27. The trigger 26,-which is hook-shaped, detachably receives the front or outer end of the connecting rod, which is provided with an eye 28 to en age the hook of the trigger. The alarm 2 which may be of any preferred construction, is preferably a burglar alarm, equipped with means for continuously ringing a bell when tripped or set 1n operation by pulling upon the trigger 26. A's any form of alarm may be employed and as the particular` construction of alarm does not constitute a portion of the present invention, a detail description and illustration of the construction of the same are deemed unnecessary. is mounted upon a bracket 29, having a horizontal supporting portion to receive the alarm and provided with a vertical attaching portion 30, which is secured by screws 31, or other suitable fastening devices :to one of the side beams'or members of the frame of the automobile. The verticzff and horizontal portions of the-bracket are connected by an L-shaped or langular portion 32, which permits the vertical attaching portion to fit between the flanges of the side bar or member 33, which is constructed of channel metal. The alarm may be"mounted on an automobile at any other desired point, and will be' preferably concealed from view so that its presence may not bedetected by a thief or other unauthorized person. When fthe rod 25 is connected to the trigger of the -larm and an attempt is made to crank the engine, the inward movement of the starting crank will engage the-inner arm or projection 10 of the shaft l1, and will oscilliate the latter, and swingthe outer arm 2O rearwardly, thereby pulling upon the trigger and operating'the alarm. When the'rodz25 is disconnected from the alarm, the engine may be cranked without operating the same. The continuousringing of the alarm will either frighten away the thief, or give notice that the machine is either stelen or operated by an unauthorized person.`

In Fig; 7 `of the .drawings is illustrated one form of electrical alarm comprising a -cam lever 3ft, pivoted at an intermediate point by 'a pin 35, or other suitable fastening device and consisting of upper andlower arms, the lower arm beingK arranged in the path of the arm 20a. The arm 20B, which corresponds with the arm 20 heretofore described, is designed to be mounted similar to theI said arm Q0. -Thejupper end of the arm 2()a is normallylocate'd in vadvance of the lower arm of Vtheicam lever, which is provided 'at its upper endywitha cam edge 36, arranged to .depress or actuate a button 37 for closing'the-circuitof 'an electric bell 38. When .the arm QOF'is' moved inwardly or rearwardly, it oscillates the cam lever and rings theelect'ricfbell. -v The arm 20B is returned to its normalA position: by a coiled spring 39, and when free to -move, thecam lever 34 isretu-rned to its initial position bya coiled spring 40.l :The electric bell maybe `located at any convenient point and instead of the push ybutton and cam lever, any

The alarm j other form of switch or Contact element may be employed.

Having thus fully described my inven- Y tion, whatl claim as new and desire to secure by Letters Patent, is:

l. In adevice of the class described, the combination with the starting crank mechanismof an automobile, an alarm, and operating mechanism f'or the alarm arranged inA the path of and adapted to be engaged by the said crankmechanism, Asaid operating mechanism being connected with the said alarm.

3. In a device'of the class described, the combination with the strating crank mechanism of an automobile, an alarm, an operating shaft having an arm or projection arranged inthe path of said crank mechanismand adapted to be engaged and actuated by the same, and means for connecting the shaft with and disconnecting it from the alarm. l

4. In a device of the class described, the combination with the starting'crank mechanism of an automobile, an alarm, a transverse Shaft having inner and outer arms, the inner arm being arranged in the path of and adapted to be engaged and actuated by said crank mechanism, and means for connecting the outer arm of the shaft with and disconnecting it from the alarm.

5. ln afdevice of the class described, the

combination with the starting crank mechanism of an automobile, an alarm having a trigger,- a transverse shaft provided with inner and outer arms, the inner arm being arranged in the path of and adapted to be engaged and actuated, by the said crank mechanism. and connecting means extending-from the outer end ofthe shaft to the trigger l.and detachably connected with the latter.
